Abstract: Apparatuses, systems, and methods are provided for assisting a driver of a motor vehicle in driving on a predeter-mined racetrack. A sensor system is configured to detect a current position of the motor vehicle on the racetrack and an electronic control unit configured to control an actuator system of the motor vehicle. Predetermined brake point positions of the racetrack are stored in the electronic control unit. A current position of the motor vehicle on the racetrack is continuously detected. A relevant remaining driving time from the current position to a relevant brake point position of the racetrack is determined using the electronic control unit. Corresponding limit values are stored in the electronic control unit for the relevant remaining driving time. When a corresponding limit value is not reached, the control device controls the actuator system of the motor such that the motor generates a signal to the driver.

Abstract: A method for providing information related to the compaction state of a soil when performing a compaction operation with a soil compactor comprises the operations: a) detecting a vertical acceleration and a horizontal acceleration of a vibratory roller when moving a soil compactor over a soil to be compacted, b) determining a measurement relationship between a ground contact force (Fb) and a deflection (sw) of the vibratory roller for one vibration cycle using the vertical acceleration and horizontal acceleration detected in operation a), c) determining a simulation relationship (ZS) between the ground contact force (Fb) and the deflection (sw) for one vibration cycle using a ground model taking into account at least one simulation parameter, d) comparing the simulation relationship (ZS) to the measurement relationship, e) determining that a default value of the at least one simulation parameter taken into account in the ground model substantially represents a corresponding soil parameter of the soil to be
